Where References Fit in the Process
Reference checks are most useful after a provisional offer has been made — conditional on satisfactory references — rather than at an earlier stage. Requesting references before shortlisting is resource-intensive and puts unnecessary burden on candidates who may be applying to multiple roles. Timing references to the end of the process also means the questions you ask are informed by what you learned in the interview, allowing you to seek specific corroboration rather than a general character endorsement.
The purpose of a reference check at this stage is two-fold: to validate the evidence gathered in the interview and confirm it is consistent with the candidate's history; and to surface any material concerns that did not emerge during the process itself.
Structuring the Reference Conversation
Unstructured reference conversations — 'Is there anything we should know?' — produce little useful information. Referees default to polite, non-committal responses because the stakes of candour are high for them. Structured reference interviews, with specific competency-based questions aligned to what the role requires, produce far more useful signal.
Effective reference questions follow the same behavioural format as the interview itself: 'Can you give me a specific example of how [candidate name] handled competing priorities?' is more revealing than 'How was their time management?'. Ask about the same competencies you assessed in the interview — the alignment or divergence between candidate self-report and referee observation is the most valuable data point.
What References Can and Cannot Tell You
References are retrospective: they tell you about a candidate's past behaviour in a specific context, with a specific team, under specific conditions. They are most informative when the referee's context is similar to the role you are hiring for. A glowing reference from a small startup environment may provide limited predictive value for a highly structured corporate role, and vice versa.
Referees self-select: candidates provide referees who are likely to speak positively about them. This limits the diagnostic value of reference checks as a standalone assessment. The absence of concerning information is not strong confirmation — it is the baseline. Specific, evidenced positive examples are the signal worth looking for.
GDPR Considerations
Under GDPR, reference checks involve the processing of personal data about the candidate. Candidates must be aware that references will be sought and, in most implementations, must provide their consent for you to contact named referees. The information shared by referees is personal data about the candidate and must be handled appropriately: stored securely, accessed only by those with a legitimate need, and retained only for as long as necessary.
Referees themselves are also sharing personal data in the call — their name, role, and opinions. Reference conversations should be conducted and recorded with appropriate care, and data shared by referees should not be used beyond the purpose for which it was provided.
How reference checks fit into a Palantrix-assisted process
When a candidate reaches the reference stage in a Palantrix process, the hiring team already has a structured evidence base: AI scores against the Team DNA Profile, full interview transcripts, and any recruiter or hiring manager notes recorded in the pipeline. This makes the reference conversation more targeted. Instead of asking general questions, you can ask specifically about the traits and competency areas where the candidate's evidence was strong — to corroborate — or where it was thin — to probe further. The full record is retained alongside the reference outcome for the EU AI Act audit trail.

How many references should you request?
Two professional references is standard for most roles — typically a recent direct manager and either a second manager or a senior peer. For senior or high-responsibility roles, three references including at least two managerial relationships is appropriate. Personal character references from friends or family carry limited professional value and are not generally used in structured hiring processes.
Can you check references without the candidate's knowledge?
No — not under GDPR in EU jurisdictions. Candidates must be aware that references will be sought as part of the hiring process. Most employers include this in their privacy notice at the application stage. Conducting covert reference checks or contacting employers not provided by the candidate without consent is both a GDPR breach and a breach of candidate trust.
What if a referee gives a negative reference?
A single negative reference requires careful interpretation. Consider whether the negative feedback relates to a competency that is genuinely critical to the role; whether it is specific and evidenced or vague and personal; and whether it is consistent with what you observed in the interview or contradicts it. A negative reference on an irrelevant dimension is not a reason to withdraw an offer; a specific, evidenced concern about a role-critical competency warrants a structured follow-up conversation with the candidate.
Should references always be taken by phone or video call?
Live references — phone or video call — are significantly more informative than written references. Written references are typically drafted by the candidate, edited by the referee, and reviewed by HR before sending, producing a highly sanitised document. Live conversations allow you to ask follow-up questions, explore hesitations, and read the nuance in a referee's responses. For any substantive hire, live references are worth the additional time.
Can an employer refuse to give a reference?
In most EU jurisdictions, employers are not legally obligated to provide a reference beyond confirming dates of employment and job title — sometimes called a 'bare bones' or 'tombstone' reference. A referee who refuses to speak beyond this is providing useful signal in itself. Former employers who do provide fuller references take on some liability for the accuracy of what they say, which is why many HR functions restrict references to factual confirmation only.
